40Ar/39Ar & (U-Th)/He Laboratory
The main instruments in this facility include an MM5400 noble gas mass-spectrometer, an Alphachron MkII He measurement instrument, a X-Series 2 ICP-MS, and associated CO2 laser fusion and 213 and 193 nm laser ablation systems. The advanced and innovative purification preparation line was developed by the members of the laboratory, and runs fully automatically. Aimed at accurate dating and mid-to-low temperature (650-70 oC) thermochronology, the research group has achieved important fruits in a number of fields such as geological dating, deep dynamics of the Earth, orogenic evolution and thermohistory, neotectonics and morphology, mineral and fossil resources, and diffusion mechanisms of noble gas. The laboratory is a well-known research platform throughout the world.
